Hello there,
Not sure is anyone can help but everytime I use the travel calculator I get this message
Access violation at address 0056a736 in module 'Astro 3.exe'. Read of address 00000030.
After this it appeared to work only all travel calaculation are locked to the origin and the system as opposed to between systems.
I have windows 7 and an Acer laptop with an ATI radeon 1g HD5650 graphics card
